Building a web application begins with outlining user roles, key scenarios, and the data model. A solid MVP concentrates on essential flows, intuitive navigation, and predictable UI components, so the product can ship rapidly without becoming a fragile collection of one-off screens.

After launch, emphasis on scalability and reliability is critical: performance budgets, caching, secure authentication, and clean API contracts. With proper monitoring, CI/CD, and thoughtful architecture, teams can iterate quickly while keeping the codebase stable as features and traffic grow.
